2023-03-07hw/xen: Watches on XenStore transactionsDavid Woodhouse
Firing watches on the nodes that still exist is relatively easy; just walk the tree and look at the nodes with refcount of one. Firing watches on *deleted* nodes is more fun. We add 'modified_in_tx' and 'deleted_in_tx' flags to each node. Nodes with those flags cannot be shared, as they will always be unique to the transaction in which they were created. When xs_node_walk would need to *create* a node as scaffolding and it encounters a deleted_in_tx node, it can resurrect it simply by clearing its deleted_in_tx flag. If that node originally had any *data*, they're gone, and the modified_in_tx flag will have been set when it was first deleted. We then attempt to send appropriate watches when the transaction is committed, properly delete the deleted_in_tx nodes, and remove the modified_in_tx flag from the others.

2023-03-07hw/xen: Implement XenStore transactionsDavid Woodhouse
Given that the whole thing supported copy on write from the beginning, transactions end up being fairly simple. On starting a transaction, just take a ref of the existing root; swap it back in on a successful commit. The main tree has a transaction ID too, and we keep a record of the last transaction ID given out. if the main tree is ever modified when it isn't the latest, it gets a new transaction ID. A commit can only succeed if the main tree hasn't moved on since it was forked. Strictly speaking, the XenStore protocol allows a transaction to succeed as long as nothing *it* read or wrote has changed in the interim, but no implementations do that; *any* change is sufficient to abort a transaction. This does not yet fire watches on the changed nodes on a commit. That bit is more fun and will come in a follow-on commit.

2023-03-07hw/xen: Implement XenStore watchesDavid Woodhouse
Starts out fairly simple: a hash table of watches based on the path. Except there can be multiple watches on the same path, so the watch ends up being a simple linked list, and the head of that list is in the hash table. Which makes removal a bit of a PITA but it's not so bad; we just special-case "I had to remove the head of the list and now I have to replace it in / remove it from the hash table". And if we don't remove the head, it's a simple linked-list operation. We do need to fire watches on *deleted* nodes, so instead of just a simple xs_node_unref() on the topmost victim, we need to recurse down and fire watches on them all.

2023-03-07hw/xen: Add basic XenStore tree walk and write/read/directory supportDavid Woodhouse
This is a fairly simple implementation of a copy-on-write tree. The node walk function starts off at the root, with 'inplace == true'. If it ever encounters a node with a refcount greater than one (including the root node), then that node is shared with other trees, and cannot be modified in place, so the inplace flag is cleared and we copy on write from there on down. Xenstore write has 'mkdir -p' semantics and will create the intermediate nodes if they don't already exist, so in that case we flip the inplace flag back to true as we populate the newly-created nodes. We put a copy of the absolute path into the buffer in the struct walk_op, with *two* NUL terminators at the end. As xs_node_walk() goes down the tree, it replaces the next '/' separator with a NUL so that it can use the 'child name' in place. The next recursion down then puts the '/' back and repeats the exercise for the next path element... if it doesn't hit that *second* NUL termination which indicates the true end of the path.

2023-03-02test-vmstate: fix bad GTree usage, use-after-freeEric Auger
According to g_tree_foreach() documentation: "The tree may not be modified while iterating over it (you can't add/remove items)." compare_trees()/diff_tree() fail to respect this rule. Historically GLib2 used a slice allocator for the GTree APIs which did not immediately release the memory back to the system allocator. As a result QEMU's use-after-free bug was not visible. With GLib > 2.75.3 however, GLib2 has switched to using malloc and now a SIGSEGV can be observed while running test-vmstate. Get rid of the node removal within the tree traversal. Also check the trees have the same number of nodes before the actual diff.

2023-02-27replay: Extract core API to 'exec/replay-core.h'Philippe Mathieu-Daudé
replay API is used deeply within TCG common code (common to user and system emulation). Unfortunately "sysemu/replay.h" requires some QAPI headers for few system-specific declarations, example: void replay_input_event(QemuConsole *src, InputEvent *evt); Since commit c2651c0eaa ("qapi/meson: Restrict UI module to system emulation and tools") the QAPI header defining the InputEvent is not generated anymore. To keep it simple, extract the 'core' replay prototypes to a new "exec/replay-core.h" header which we include in the TCG code that doesn't need the rest of the replay API.

2023-02-01block: Convert bdrv_refresh_total_sectors() to co_wrapper_mixedEmanuele Giuseppe Esposito
BlockDriver->bdrv_getlength is categorized as IO callback, and it currently doesn't run in a coroutine. We should let it take a graph rdlock since the callback traverses the block nodes graph, which however is only possible in a coroutine. Therefore turn it into a co_wrapper to move the actual function into a coroutine where the lock can be taken. Because now this function creates a new coroutine and polls, we need to take the AioContext lock where it is missing, for the only reason that internally co_wrapper calls AIO_WAIT_WHILE and it expects to release the AioContext lock. This is especially messy when a co_wrapper creates a coroutine and polls in bdrv_open_driver, because this function has so many callers in so many context that it can easily lead to deadlocks. Therefore the new rule for bdrv_open_driver is that the caller must always hold the AioContext lock of the given bs (except if it is a coroutine), because the function calls bdrv_refresh_total_sectors() which is now a co_wrapper. Once the rwlock is ultimated and placed in every place it needs to be, we will poll using AIO_WAIT_WHILE_UNLOCKED and remove the AioContext lock.

The test case assumes that a drain only happens in one specific place where it drains explicitly. This assumption happened to hold true until now, but block layer functions may drain interally (any graph modifications are going to do that through bdrv_graph_wrlock()), so this is incorrect. Make sure that the test code in .drained_begin only runs where we actually want it to run.

This is possible now because we can require that the parent is already drained through the child in question when the function is called and we don't call the parent drain callbacks more than once. The additional drain calls needed in callers cause the test case to run its code in the drain handler too early (bdrv_attach_child() drains now), so modify it to only enable the code after the test setup has completed.

A second drain section doesn't make a difference for the driver or the parent, they weren't supposed to send new requests before and after the second drain. One thing that gets in the way is the 'ignore_bds_parents' parameter in bdrv_do_drained_begin_quiesce() and bdrv_do_drained_end(): It means that bdrv_drain_all_begin() increases bs->quiesce_counter, but does not quiesce the parent through BdrvChildClass callbacks. If an additional drain section is started now, bs->quiesce_counter will be non-zero, but we would still need to quiesce the parent through BdrvChildClass in order to keep things consistent (and unquiesce it on the matching bdrv_drained_end(), even though the counter would not reach 0 yet as long as the bdrv_drain_all() section is still active). Instead of keeping track of this, let's just get rid of the parameter. It was introduced in commit 6cd5c9d7b2d as an optimisation so that during bdrv_drain_all(), we wouldn't recursively drain all parents up to the root for each node, resulting in quadratic complexity. As it happens, calling the callbacks only once solves the same problem, so as of this patch, we'll still have O(n) complexity and ignore_bds_parents is not needed any more. This patch only ignores the 'ignore_bds_parents' parameter. It will be removed in a separate patch.

2022-12-15block: Revert .bdrv_drained_begin/end to non-coroutine_fnKevin Wolf
Polling during bdrv_drained_end() can be problematic (and in the future, we may get cases for bdrv_drained_begin() where polling is forbidden, and we don't care about already in-flight requests, but just want to prevent new requests from arriving). The .bdrv_drained_begin/end callbacks running in a coroutine is the only reason why we have to do this polling, so make them non-coroutine callbacks again. None of the callers actually yield any more. This means that bdrv_drained_end() effectively doesn't poll any more, even if AIO_WAIT_WHILE() loops are still there (their condition is false from the beginning). This is generally not a problem, but in test-bdrv-drain, some additional explicit aio_poll() calls need to be added because the test case wants to verify the final state after BHs have executed.

2022-12-15test-bdrv-drain: Don't yield in .bdrv_co_drained_begin/end()Kevin Wolf
We want to change .bdrv_co_drained_begin/end() back to be non-coroutine callbacks, so in preparation, avoid yielding in their implementation. This does almost the same as the existing logic in bdrv_drain_invoke(), by creating and entering coroutines internally. However, since the test case is by far the heaviest user of coroutine code in drain callbacks, it is preferable to have the complexity in the test case rather than the drain core, which is already complicated enough without this. The behaviour for bdrv_drain_begin() is unchanged because we increase bs->in_flight and this is still polled. However, bdrv_drain_end() doesn't wait for the spawned coroutine to complete any more. This is fine, we don't rely on bdrv_drain_end() restarting all operations immediately before the next aio_poll().

2022-10-27block: Manipulate bs->file / bs->backing pointers in .attach/.detachVladimir Sementsov-Ogievskiy
bs->file and bs->backing are a kind of duplication of part of bs->children. But very useful diplication, so let's not drop them at all:) We should manage bs->file and bs->backing in same place, where we manage bs->children, to keep them in sync. Moreover, generic io paths are unprepared to BdrvChild without a bs, so it's double good to clear bs->file / bs->backing when we detach the child. Detach is simple: if we detach bs->file or bs->backing child, just set corresponding field to NULL. Attach is a bit more complicated. But we still can precisely detect should we set one of bs->file / bs->backing or not: - if role is BDRV_CHILD_COW, we definitely deal with bs->backing - else, if role is BDRV_CHILD_FILTERED (it must be also BDRV_CHILD_PRIMARY), it's a filtered child. Use bs->drv->filtered_child_is_backing to chose the pointer field to modify. - else, if role is BDRV_CHILD_PRIMARY, we deal with bs->file - in all other cases, it's neither bs->backing nor bs->file. It's some other child and we shouldn't care OK. This change brings one more good thing: we can (and should) get rid of all indirect pointers in the block-graph-change transactions: bdrv_attach_child_common() stores BdrvChild** into transaction to clear it on abort. bdrv_attach_child_common() has two callers: bdrv_attach_child_noperm() just pass-through this feature, bdrv_root_attach_child() doesn't need the feature. Look at bdrv_attach_child_noperm() callers: - bdrv_attach_child() doesn't need the feature - bdrv_set_file_or_backing_noperm() uses the feature to manage bs->file and bs->backing, we don't want it anymore - bdrv_append() uses the feature to manage bs->backing, again we don't want it anymore So, we should drop this stuff! Great! We could probably keep BdrvChild** argument to keep the int return value, but it seems not worth the complexity. Finally, we now set .file / .backing automatically in generic code and want to restring setting them by hand outside of .attach/.detach. So, this patch cleanups all remaining places where they were set. To find such places I use: git grep '\->file =' git grep '\->backing =' git grep '&.*\<backing\>' git grep '&.*\<file\>' Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@yandex-team.ru> Reviewed-by: Hanna Reitz <hreitz@redhat.com> Message-Id: <20220726201134.924743-14-vsementsov@yandex-team.ru> Signed-off-by: Kevin Wolf <kwolf@redhat.com>

test_parallel_perm_update() does two things that we are going to restrict in the near future: 1. It updates bs->file field by hand. bs->file will be managed automatically by generic code (together with bs->children list). Let's better refactor our "tricky" bds to have own state where one of children is linked as "selected". This also looks less "tricky", so avoid using this word. 2. It create FILTERED children that are not PRIMARY. Except for tests all FILTERED children in the Qemu block layer are always PRIMARY as well. We are going to formalize this rule, so let's better use DATA children here. 3. It creates more than one FILTERED child, which is already abandoned in BDRV_CHILD_FILTERED's description.
